A giant inflatable chicken, the latest protest stunt against President Trump, appeared outside the White House on Wednesday afternoon. It was the brainchild of Taran Singh Brar, an artist and documentary filmmaker based in Washington.

Mr. Brar said in a video on CGTN’s website that he had the idea in March to haul that chicken to the Ellipse near the White House. It took four months of planning and getting the right permits for his plan to come to fruition.

The Run-Up

The podcast that makes sense of the most delirious stretch of the 2016 campaign.

But why, pray tell, a chicken? And especially one that comes with a name, Chicken Don or Donny, and a Twitter account, @TaxMarchChicken?

“Images speak a thousand words, and the daily fire hose of lies from Trump is pretty deflating, like Chicken Don right now,” Mr. Brar says in the CGTN video.

“He’s too afraid to release his tax returns, too afraid to stand up to Vladimir Putin, and playing chicken with North Korea,” he was quoted as saying.

Mr. Brar is not the first to unfurl an eye-popping symbol of political discontent aimed at Mr. Trump. Last year, an anarchist group called INDECLINE displayed orange nude life-size statues of the presidential candidate in several American cities, including in a park in New York.

When the 30-foot bird with the golden coif appeared this week on the Ellipse, a park directly south of the White House in view of the Washington Monument, onlookers had no trouble identifying its human doppelgänger.

The chicken’s furrowed golden brows make it look angry. Its feathered crown is side-swept to resemble Mr. Trump’s hairstyle, which sometimes seems to defy the laws of physics.

The chicken sports a bright red wattle, the fleshy comb found below a rooster’s beak — echoing the president’s favorite color of necktie.
